The top and end walls/5'7, 7 ofthe'door opening 7 provide a box like structureformedof sheet metal. The endofthe opening 7:is coveredby screen carryin'gframe 7 .1

The door 8 is also members 10, 1'1 and abottom member 12. The bottom member "12 is an angle ironsecured' at its endasiby welding to the side frame.

Theleaves are secured in position by rivets or in any other suitable manner. The door is also formed with end walls 18 and top wall 19 telescoping into the opening 7 and these are spaced apart or set in from the flange 17. and

slidably fit on the opposing faces ofthe angular flange 13 or the parts thereof which form the channel 14. The top is formed with perforations which provide ventilating passages' The top wall is provided with a stop shoulder 20 at its rear edge for engaging the rear side of the door frame when the door is in full open position.

The door is provided with a hand hold located on the rear side thereof, this hand hold being a plate 22 lapping the rear faceiof the door and having a depressed or'socket portion 23 in line with a passage formed in the door. The plate is secured into position by screws 25 passing through aface plate 26 on the front side of the door and through the door and threading into the plate 22. The face plate has an opening 27 inline withthe hand passage in the door. V 1

The means for holding the door in closed and in a plurality of open positions coacts with the hand hold and is located midway between the ends of, the door or in line with the hand hold. This holding means as here shown comprises a spring pressed arm 30 pivoted to a bracket 31 mounted on the bottom wall 6 of the door opening and inclining upwardly and having a' roller 32 at its upper edge which coactswith the lug33 on the'hand hold.- The lug is formed with a'plura'lity of seats. I The lug is shown as rectangular in form and projects rearwardlvj When the door is closed the roller is seated onthe upper side of the lug and when the door is open in different positions the rollerseats in'any one of a number of seats or recesses 34 in the-rear end of the lug. f f 1 i i The bracket 31 comprises a'baseplate 35 and a pair of cars projecting upwardly from the base plate in which the pivot pin for the arm 30 is mounted; and the spring. 36 is e coiled about the pivot and anchored at one end thereof to one of the'ears of the bracket,

" at its other end to a pin 37 onfarm '30.. The

arm 30 is formed double with a roller 32 and pin 37 between the branches thereof.' The base plate 35is secured to the bottom wall 6 to the opening 3 in any suitable manner as by rivets 38.

' Owing to the location of this holding means between the ends of the door or in line with the hand hold, sticking of the holding means is avoided, also the operation of the door is greatly facilitated by the coaction of the locking arm directly-With the hand hold plate as the hand hold is usually a rigid casting while the remainder of the door is of sheet metal. Furthermore, owing to the location of the holding means theforce applied to open or close the door, is transmitted directly through the rigid hand hold and is not affected by pos sible flexing of the sheet metal parts due to thedoor sticking in the door opening.

Owing to the construction of the door frame and the door, the dooris weather tight when closed and flush with the outer face of the door frame. Furthermore, owing to the construction of the door frame it is readily applied to a frame member or window sill.

This door frame construction is furthermore particularly efficient in that it permits the major part of the structure to be formed up of'sheet, metal instead of castings, and is sufficiently rigid to withstand the strains to which it is submitted.

What Iclaim is: ,7 1. The combination witha frame member having a ventilatoropening therethrough, of

a doorin said opening, the door being hinged at one edge and having side walls and a wall at its free edge telescoping into said opening,

the wall at the free edge being formed with ventilatorpassages therethrough, the door being also provided with a hand passage therethrough and a hand holdmounted on the inner side of the door provided with a depressed portion closing said opening in the door and impositive locking means for holding the door in open and closed positions, and means carried by the hand hold with which said locking means coacts to hold the door in adjusted position. V v r l 2. The combination with a framemember having a ventilator opening therethrough, of a door in said opening, the door being hinged at one edge and having side walls and a wall at its freeedge telescoping into said opening, the wall at the free edge being formed with ventilator passages therethrough, the door being also, provided with a hand passage therethrough and a hand hold mounted on the inner side of the door provided with a depressed portion closing said opening, the hand hold being provided with a keeper plate located near the hinged edge of the door and a spring pressed member mounted in the opening in the frame member and coacting with said keeper plate.

. 3. The combination with a frame member ing and having wallstelescoping' into the having an opening therethrough, of a sheet metal door hinged at one edge in said openopening, a stiffening member secured to the door between theends thereofand having holder engaging means on the inner side of the door and spring pressed holder means coacting with said former means for holding the door in difierent angular positions, said stiflening member being formed with a hand 7 7 hold exposed on the outer side of the door.

In testimony whereof, 'I have hereunto signed my name, at Syracuse, in 'the county of Onondaga, in the State of New York, this 7 27th day of September, 1927.
